ond through each plug is e central aperture through which passes thespringpressed plungenf), having a head 9, -and a spring 9b. These guidesare rectangular shapey in cross section with one side open and theoutside face is slotted as et l0, so that the screen may be inserted bypassing it through the slot/10 and raising it above the top of the guideuntil the lower end drops in the guide when itis then pulled downto itsposition of rest. The screens are provided with s screen frame 11 at themargins and the bottom of the screen frame 1l of the screen D,

rests upon the periphery of the Contact strip i roll 5, while the top ofthe strip, 11 of the lowerscreen E is pressed against the com tact strip4. The periphery of the contact strip 5 where the screen wipes it is theshape oia segment ofc circle in cross section and the radii thereof areof such calculated length that the sash. in revolving brings the Contactstrip always in contact with the stationary .screen D. The upper screenis held yieldingly against the contact strip 5 by gravity. The contactstrip 4 is of o ditlerent shape (as shown in. the drawings), its shapenot beings() material, providing its contour curately against the lowerscreendfrarnes of' the upper screen D and the roll l depresses thescreen E in its guides, and slides across its upper frame bar.
